This is concerned with a surface cleaning machine such as a burnisher or scrubber and is more particularly concerned with a quick connect/disconnect holding and centering structure for high speed brush and pad use which is specifically constructed to accurately center a brush or pad and dampen any vibration so that the brush or pad may be operated at a high speed without special balancing, as well as to allow for each and quick connect or disconnect. The holding and centering structure comprises an opening in the center of a surface cleaning element adapted to receive a driven hub fitted down in the opening. A circumferential formation in the opening is adapted to interferingly bypass a complementary circumferential formation on the hub. One of the circumferential formations is uniformly distortable.

In a quick connect/disconnect coupling for use in a surface cleaning machine or the like, a surface working tool with an opening in the center thereof, a generally circular ring connected to the working tool and disposed in its center opening, a drive hub adapted to be fitted down in the ring, an elastic toroid between the ring and hub mounted on one of them and opposing the other, an interference circumference on the other constructed so that when the ring and hub are axially brought together under a certain amount of force, the cirfumference and toroid interferingly bypass each other due to elastic distortion of the toroid, and a plurality of circumferential interlocks between the ring and hub that interfit to transmit rotation from the hub to the ring and working tool.
