A coupler is provided which responds to relative rotation of a driving and a driven shaft with variable rates of stiffness. As the two shafts experience slight degrees of relative rotation, such as at idle speed, the elastically deformable member of the coupler responds in a relatively soft manner with a slight degree of stiffness. As relative rotation increases because of the transmission of higher torque between the driving and driven shafts, the elastically deformable member responds with a stiffer reaction. The elastically deformable member also reacts in a similar manner with differing rates of stiffness to misalignment of the driving and driven shafts.
