Abstract
Abstract A joint between drive and driven shafts necessitating alignment therebetween comprises a first and second flanged socket adapted to rigidly retain therein a drive and driven shaft respectively. A disc of resilient material is located between the flanged sockets and is rigidly connected thereto. The disc has means on its outer periphery to radially restrain outward movement of the disc. A self-aligning bearing is located between the annular disc and the first flanged socket. The annular disc and bearing are adapted to receive an inner end of the driven shaft.
