A slip clutch for use in a bin level indicator or the like between a motor operated driving shaft and a driven shaft which rotates paddle means adapted to be impeded or stopped by the rising material in a bin or the like, comprising a hollow end portion on the driven shaft, the driving shaft being rotatably received in an axial bore in such hollow end portion, and a spring loop mounted around the hollow end portion for rotation therewith, such hollow end portion having a cutaway portion forming a recess communicating with such bore, the driving shaft having a flat surface on one side thereof, the spring loop extending into such recess and initially into engagement with such flat surface to transmit torque between the driving and driven shafts, the spring loop being flexible outwardly by the flat surface on the driving shaft to provide for slipping between the driving shaft and the driven shaft when the torque being transmitted by the slip clutch exceeds a predetermined value, the spring loop preferably being made of spring wire.
