South Africa-born Curran, who qualifies for England at the end of October, took two seven-wicket hauls in the Championship and on Saturday was added to the England Performance Programme squad.
Rushworth's 100 wickets came at an average of 20.61 and set a new record for Durham, surpassing Ottis Gibson's 83 wickets in a season. The Sunderland-born bowler also took home the PCA's county most valuable player (MVP) award.
"To be voted for by fellow players and your peers is a very privileged moment and one I'm very proud of," Rushworth said.
"The guys that have won it in recent years have gone on to play Test cricket so that is definitely in my sights.
"Hopefully I have another good season next year and I can put my name in the hat for Test selection."
England seamer Stuart Broad was named Test player of the summer, while pace bowler Anya Shrubsole picked up the women's player of the summer award.
