The linkage comprises a rocker having a rigid body portion, the body portion including a pivot axis about which it is rotatable, and a link mount for coupling to a valve link arm. The link mount is moveable from a rest position relative to the body portion, and the link mount is urged back towards its rest position when displaced from its rest position relative to the body portion.
