Abstract
A sprinkler includes a riser, an impeller mounted in the riser, and a nozzle rotatably mounted at an upper end of the riser. A drive assembly couples the impeller and the nozzle. A clutch in the drive assembly includes a radially deformable collet that surrounds a drive shaft. A spring urges the collet against the drive shaft and provides a positive drive connection under a normal load and slips under an excessive load.
