description The invention relates to a device for attachment to a domestic vacuum cleaner to clean floor coverings and the like. More particularly, the invention relates to a drive coupling for use in the device. The drive coupling consists essentially of an inner element connected to an outer element by straps and a spring positioned between the elements for biasing the elements apart and extending the straps. The drive coupling is positioned between an output from a turbine and a brush for transmitting torque from the turbine output to the brush. When the brush meets an increased resistance in cleaning the floor covering, the straps move from their normal axial position into an inclined position thereby elevating the brush and reducing the resistance to rotation for limiting the effects of the resistance on the turbine.
