A clutch driven disc assembly includes a hub, a support plate and at least one reinforcing plate mounted on and rotatable relative to the hub, a plurality of circumferentially spaced fasteners connecting together the support plate and the reinforcing plate, and a coaxial spring damper. In an alternate embodiment, the support plate is attached to one of a pair of outer covers positioned on opposite sides of a flange radially extending from the hub and rotatable relative to the hub. An apparatus for adjusting hysteresis in the damper includes a backing plate mounted on the hub with facing material abutting either the fasteners or the other cover for applying an axial load to the support plate. The load is selectively adjustable through a threaded locking nut and wave washer mounted on the hub.
