A constant velocity torque transmitting joint comprises an outer joint member having a bore therethrough and an inner joint member positioned within the bore. A plurality of torque transmitting elements, such as balls, are positioned within pairs of opposed grooves formed in the opposing surfaces of the inner and outer joint members. A cage is disposed between the joint members and has a plurality of openings in which the balls are retained. The cage has an inner concave surface guided upon a separate alignment control device supported upon the inner joint member. The cage also has an outer spherical surface which is guided within the bore. The alignment control device comprises at least three control elements in the shape of balls, cylindrical rollers or barrel-shaped rollers supported in recesses provided between pairs of adjacent track grooves in the inner joint member. The centers of the control elements and of the cage inner concave surface are positioned in a common plane.
