Constant velocity, torsionally rigid, flexible coupling

Abstract From the Canadian patent

A flexible coupling comprises first and second torque transmitting members capable of being rotated about first and second axes, respectively. The coupling also includes connecting members associated in pairs. The connecting members are connected together and to the torque transmitting members through suitable bearings, preferably of the elastomeric type, for carrying pure compressive stress loading for torque transmission and for providing shear motion and restoring forces when said axes become misaligned.
