A device adapted for pulling the ends of a continuous chain together, with each chain end including a link, in order to measure the tension in the chain. The controller is programmed to monitor a maintenance condition of the electronic faucet and to selectively open and close the valve to generate a fluid flow pattern through the passageway to provide an indication to a user of an existing maintenance condition. Significantly, when the pad member is molded directly to the body member, the pad has internal dimensions only slightly larger than the external dimensions of the body member so that, when the body member is located within the confines of the pad member, a secure fit is formed between these two members, without any space between them. A first torque transmission path is provided between the input region and output region, and a second torque transmission path is provided parallel thereto.
