Abstract
A shaft assembly for an aircraft engine includes a first shaft coupled to a second shaft with a splined coupling made of an electrically-insulating material. The first and second shafts and the splined coupling are rotatable about an axis. A positioning device is mounted to the splined coupling and to the first shaft about the axis. The positioning device is displaceable along the axis relative to the first shaft to vary an axial position of the splined coupling.
