A gas turbine engine comprises, in axial flow sequence, a fan assembly, a compressor module, a turbine module, and an exhaust module. The gas turbine engine comprises first and second engine mount planes. The first and second engine mount planes are configured to support gas turbine engine in machine body. The gas turbine engine has axial length L, with axial length extending from inlet face of engine to exhaust face of engine. The first engine mount plane is positioned axially along gas turbine engine at first engine mount plane position, with first engine mount plane position within a range of between 0.24*L to 0.32*L from the inlet face of the engine. The second engine mount plane is positioned axially along gas turbine engine at second engine mount plane position, with second engine mount plane position within a range of between 0.73*L to 0.79*L from the inlet face of the engine.

A fail-safe electromagnetic linkage has a support device for a valve head, and an actuator component actuable by an actuator. The support device is coupled to the actuator component while power is supplied to the electromagnet and decoupled from the actuator component while power is not supplied to the electromagnet. The assembly further comprises a return mechanism configured to drive the support device relative to the actuator component if power is not supplied to the electromagnet.
