The wobble plate includes a hollow spherical outer bearing opening. A bearing arrangement includes rolling bearing balls and a ball cage movably arranged in the outer bearing opening and delimits a hollow spherical inner bearing opening. The ball cage includes window openings in which the rolling bearing balls are arranged. The coupling portion has first round grooves for the rolling bearing balls and the outer bearing opening has second round grooves for the rolling bearing balls.
