A surgical instrument includes a handle, an adaptor, and a non-contact electrical interface. A proximal end of the adaptor is releasably coupled to a distal end of the handle. The non-contact electrical interface is configured to wirelessly transmit energy from the handle to the adaptor and is configured to wirelessly transmit data from the adaptor to the handle. The electrical interface may include a proximal coil disposed within the handle and a distal coil disposed within the adaptor. When the adaptor is coupled to the handle, the proximal coil may be disposed adjacent the distal coil to form a transformer to inductively transfer energy from the handle to the adaptor and inductively transmit data from the adaptor to the handle.
