Abstract: A torque transmitting device having a spring pack assembly, includes a first spring retainer ring abutting the hydraulically actuated piston, a second spring retainer ring abutting the piston housing, and a plurality of coiled springs biasing the first spring retainer ring apart from the second retainer ring, thereby urging the hydraulically actuated piston slideably apart from the fixed piston housing. The first and second spring retainer rings includes a plurality of radially extending spring support surfaces defining center openings and a plurality of axially extending tabs. The first and second spring retainer rings are coaxially disposed such that the plurality of tabs of one spring retainer ring extends through the opening of the other spring retainer ring. The tab includes a width sufficiently wide to support the inner diameter of the coiled spring to prevent the spring from bowing out.
