The drive shaft is provided with concentrically disposed spacers, rollers, and bearings which are compressed between an end driving sprocket and an adjustable spring pressure plate on an opposite end and wherein adjustment of the axial compressor force produced by the end mounted spring pressure plate serves to vary the release torque of the individual rollers mounted on the shaft.
