A coupling for use with two relatively movable members to transmit force between said members comprising a resilient element having a plurality of convolutions positioned between the members and a solid core element positioned within the convolutions of said resilient element, said resilient element being positioned such that the relative movement of said members urges said convolutions into frictional engagement with both of said members. The solid core element is of a size such that when frictional engagement of said members with said convolutions occurs, the convolutions are prevented from being distorted beyond their elastic limit to thereby cause permanent set of the resilient element.
