Zusammenfassung:	The present invention relates to a swivel for the reduction of twist of a rope, having two swivel parts which are rotatable with respect to one another in the longitudinal direction of the rope, wherein a rotary drive is provided for the forced rotation of the two parts with respect to one another. In accordance with the invention, at least one direction of rotation measurement unit is provided at the swivel for the detection of the direction of twist of the rope with respect to the swivel, wherein the rotary drive can be controlled by a control apparatus in dependence on the determined direction of twist such that the swivel part connected to the rope is rotated in the direction of the detected direction of twist.
