Abstract
A coupling transmits torque between two shafts approximately aligned on a shaft axis. The coupling has a center axis approximately aligned with the shaft axis. The coupling comprises arcuate coupling segments with ends extending generally parallel to the coupling center axis and arcuate portions extending between the ends. The arcuate coupling segments are arranged in a ring with adjacent segments being arranged end to end to form the coupling. Each coupling portion comprises a first clamp ring adapted to be operatively attached to a shaft and a second clamp ring adapted to be operatively connected to another shaft. Elastomer material extends between both clamp rings. The elastomer material extends axially and circumferentially on each clamp ring in areas adjacent to each end of the arcuate coupling segment.
