A torsion spring for connecting a first member and a second member that are aligned along a longitudinal axis and that rotate about that axis together. The torsion spring includes a first molded plastic end that mates with the first member, a second molded plastic end that mate with the second member, and an elastic member that connects the first and second molded plastic ends together. The elastic member is for providing a force that biases the second member relative to the first member. The elastic member can be made of molded plastic arms or an elastic compound such as rubber.
