Abstract
There is disclosed a compression loaded torsional coupling device for use in drive shafts to provide a resilient interface between input and output portions of the shaft. Elastomeric cushions between fins extending in alternating fashion from opposed coupling members provide the resiliency. The coupling is produced by a unique process. Elastomer is first inserted into alternating gaps between adjacent fins. This elastomer is then compressed by applying a torque to rotate the coupling members with respect to each other. Elastomer is then placed in the remaining gaps. The torque is then released, permitting the compressive forces to redistribute in the elastomeric material around the circumference of the coupling.
