Torbay victor Adrian Sanders gets a kiss from wife Alison
Fellow Tories Gary Streeter held Devon South West, Angela Browning held Tiverton, Anthony Steen held Totnes and Hugo Swire held Devon East.
Lib Dems Adrian Sanders, Richard Younger-Ross and Nick Harvey held Torbay, Teignbridge and Devon North.
Labour's Linda Gilroy and Alison Seabeck held Plymouth Sutton and Devonport and Ben Bradshaw held Exeter.
Devon West victor Mr Cox increased the Conservative share of the vote by 2.7% to win by 3,236 votes, while the Liberal Democrats lost 5%.
Former Liberal Democrat MP John Burnett had vacated the seat which he won in 2001 with an extremely slender majority of 1,194.
"I'm tremendously honoured by the trust the people of Torridge and West Devon have put in me and I congratulate my opponents for a tough and honourable fight," said Mr Cox.
The Torbay result showed a fall in Mr Sanders' majority over the Conservatives from about 6,000 in 2001 to just over 2,000 in 2005.
The Labour vote of 6,972 was up from a 9.4% share to 14.7%. UKIP went from 3.2% of the vote to 7.9%.
In Plymouth Sutton, Linda Gilroy had a majority of 4,109, winning 40.6% of the vote.
The main beneficiaries were the Lib Dems who saw their share of the vote rise from 14.3% to 22.9%.
Labour's Alison Seabeck had a majority of about 8,000 at Plymouth Devonport, despite a 6% swing from Labour to the Conservatives.
In Devon South West, Mr Streeter saw his majority fall slightly to just over 10,000.
But he said he was pleased with progress the Conservatives had made.
"It feels good to be a Conservative, " he said.
The Lib Dems increased their share of the vote by 5.7% to edge ahead of Labour, which was in third place and down 8%.
In Teignbridge, Richard Younger-Ross fended off a Conservative challenge from Stanley Johnson, father of Conservative MP Boris.
Mr Johnson saw a fall of nearly 4% in the overall vote for the Conservatives, but he said the campaign was "very good fun".
UKIP party leader Roger Knapman won only 3,914 votes in Totnes, which was held by Conservative Anthony Steen despite a strong challenge from Liberal Democrat Mike Treleaven.
In Exeter, where there was a 64.8% turnout, Ben Bradshaw saw an 8.7% fall in his majority but said he was pleased with a "solid" result.
"It would have been amazing to repeat the highs of 1997 and 2001.
"It's a solid majority in a seat that always used to be Conservative and I think it shows how far the Tory party still has to go," he said.
