I can't tell exactly what is broken. The handle turns, but nothing happens, so something inside that plate is broken. The plate is riveted to the backing plate and I can't even see or tell where the handle mounts to it (no visible screws). There are no screw heads on the outside of the handle either, just round, smooth heads (like a small carriage bolt head).
