Abstract
An actuator for rotation of coupling means such as a loop in a high frequency resonant cavity includes a rotatable member to which the loop is fixed and a rod located adjacent it. The member and rod have interengaging teeth such that when the rod is moved inwardly or outwardly by an operator it causes the member, and hence the loop, to rotate. This is a compact assembly having components which are simple and easy to facilitate. In a preferred embodiment, the rod is located in a groove in the cavity wall.
