A power transfer system consisting of sprocket housings whose ports are inter-connected by flexible or formable or pre-shaped tubes, the tubes and the sprocket housings forming an endless track through which a plurality of juxtaposed spheres or balls are passed. The rotation of a sprocket in one housing causes transfer of the balls in their continuous path so as to rotate the sprocket in the other housing. Each sprocket is bifurcated and an arcuate member is placed adjacent the sprockets to facilitate the transfer of the balls from the housings to the tubes. A quick disconnect assembly is provided between the ports of each housing and the tubes, by which the tubes may be readily disconnected. The inadvertent discharge of the balls from the tubes and the housings is prevented by check members. The sprocket of the present invention cooperates, in certain embodiments with a pinion or a rack or a worm gear or a planetary arrangement.
