Abstract
Abstract Two shafts which are at least approximately parallel and rotate about transversely spaced axes connected by a torque transmission arrangement consisting of two axially spaced radial flanges on respective end portions of the shaft, three eccentric pins equiangularly distributed about the axis of each shaft and axially projecting from each flange toward the plane of rotation of the other flange, and three links of equal length hingedly connecting corresponding pins on the two flanges. When two such arrangements are connected in series by a flexible coupling between the two shafts, the shafts may be angularly misaligned by a small acute angle.
