Abstract
The device of the present invention provides a mechanism which arranges a set of elastomeric blocks, one adjacent the other, in separate housings, so as to limit rotation between an input and an output of the housings and in which a surface of a bushing arrangement cooperates with the device so as to limit rotation of a shaft and housing arrangement of the bushing. The structural arrangement limits radial loading and, improves wear life of the elastomeric block.
