Abstract
A compact torque limiting clutch provides spring cup bolt assemblies for interengaging a pressure plate and input plate and input flange on opposite sides of a friction flange of an output hub. The spring cup assemblies include bolts employed for securing the clutch elements together, such bolts being restricted from rotating during the assembly process by engagement with noncircular apertures passing through the retainer plate. The torque limiting clutch is of a pancake design, contained between axially displaced planar surfaces defined by an input flange on one side and a pressure plate on the other.
