A second joint member is also included having a second rotational axis and three arms extending into the respective tracks of the first joint member. Each of the arms has a respective arm axis, and a roller is carried by each arm. Each roller has a roller axis and an external circumferential surface which engages opposite sides of the respective track in the first joint member.
