A variable geometry turbine actuator rod 116 comprising a head 127 for attachment to a moving wall, and a stem, or shaft 134, extending from the head and which is connected to an actuator. One of the head and stem defines a projection extending parallel to the longitudinal axis of the stem and the other defines a complementary recess for receipt of the projection so as to resist relative rotation between the head and the stem. The invention improves the alignment of the stem and head during the assembly process and allows the components to be assembled without a bespoke assembly fixture, providing flexibility in the production chain as to when to perform the assembly operation. Also disclosed is an actuator rod comprising a head and a stem, wherein the stem comprises a hollow bushing defining a bore; and a shaft defining a region, for receipt by the bore of the hollow bushing. |
