Abstract
A flexible shaft assembly that transfers torque from a driver to a driven member includes a stub shaft that includes an elongated shaft axis, where the stub shaft couples to the driver, and a flexible coupling that includes a first hub that is adjustably connected to a second hub, where the second hub is coupled to the driven member and includes an external cylindrical interface. The flexible shaft assembly further includes a spacer that includes a spacer body, a shaft clearance hole that passes through the spacer body having a central axis extending therethrough, and a cylindrical guide surface concentric with the shaft clearance hole, where the external cylindrical interface of the flexible coupling is located inside the cylindrical guide surface, and the first hub adjusts relative to the second hub when the elongated shaft axis is out of alignment with the central axis of the shaft clearance hole.
