Abstract

A mechanism for actuating movement of an element of a gas turbine engine has a connection rod 51 for transmitting movement between two components (one shown 52). The rod 51 extends between two joints (one shown at 50) which couple the rod 51 to the components 52. At least one of the joints 50 has an eccentric or off-centre arrangement which allows the position of the corresponding end of the rod 51 to be translated relative to the respective component 52. The eccentric arrangement may take the form of a bush 54 with an off centre cylindrical passage 56.
