A rotary joint mechanism for connecting two machine parts to effect relative movement between the two machine parts includes an outer ring adapted to be connected to a rotatable machine part, and an inner ring adapted to be connected to a fixed machine part, with the outer ring being rotatable relative to the inner ring. The outer surface of the outer ring is provided with a mechanism for transferring force from at least one cable element to the outer ring to effect rotation of the outer ring relative to the inner ring.
