System for converting manually-operated flush valves

A conversion assembly for converting an installed manually-operated flush valve used with a urinal or toilet, comprising:

• a power module, a control module, and a driver module arranged for mechanical coupling to a manual handle of said manually-operated flush valve,
• said driver module includes a gear mechanism mechanically coupled to displace said manual handle of a flush valve, and
• said driver module being mechanically attached relative to a body member of the flush valve
• wherein said driver module is mechanically attached to a coupling nut used to attach said manual handle to a body of the flush valve.
