A rotary coupling (10) comprises a rotatable set of primary gear teeth (20), a damper (14) having a set of complementary secondary gear teeth (52) engagable with the primary gear teeth (20), and a damper guide, preferably being a damper channel (38),associated with the hub body (16) along which the damper (14) can move. To damp rotation of the primary gear teeth (20), the secondary gear teeth (52) are movable into and out of engagement with the primary gear teeth (20) dependent on a tilt of the damper guide (38). A method of damping rotational movement of a rotatable element, preferably being a wheel,and preferably using such a rotary coupling (10), is also provided. |
