The invention relates to the transmission of power and/or data from/to a stationary part of a machine toolto/from an accessorymounted in the spindleof the machine tool. A first electrical link or interfaceprovides electrical communication between the stationary partand the spindle, and a second electrical link or interfaceis provided electrically connected to the first electrical link at the accessory mounting area. The second linkis in the form of electrical contacts. The invention extends to an accessory shankfor mounting to the spindleof the machine tool, and also to an accessorye.g. in the form of a measurement probe, connected to the said shank

Transmission of power and/or signal across a machine tool spindle shank is disclosed. Contacts () on the shank are connectable to tracks () on the spindle (). A circuit (e.g. FIG.) is used to determine the orientation of the contacts relative to the tracks when the shank is inserted in an unknown orientation into the spindle.
