Be very careful with the coupling ring as the wiper brush is very fragile.
Often, just a cleaning of the outer edge of that ring will make it return
properly. Other rings are damage by lenses that are missing the "stop"
screw. Lens is forced passed it's stop, also forcing the coupling ring too
far, distorting it into an oval shape.
