A capping apparatus and a magnetic coupling assembly therefor comprises a capping head for applying a cap, a drive mechanism for driving the capping head, and a separable magnetic coupling for selectively coupling the capping head to the drive mechanism. The separable coupling is operable to selectively drive the capping head at an initial rotational speed and for selectively de-coupling the capping head from the drive mechanism while the capping head is rotating. This allows the capping head to be moved toward a container to place the cap on the container while preventing the drive mechanism from continuing to drive the capping head as the cap is placed on the container.
