An assembly usable with a bottom hole assembly in a wellbore can include a fixed housing member coupleable to a bent housing member at a housing coupling location. The bent housing member can rotate relative to the fixed housing member and can include an offset opening for receiving a drive shaft. The assembly can include an RFID tag positioned on a piston that is slideably positioned within the fixed housing member. An RFID reader can be positioned on the fixed housing member for detecting the RFID tag in response to the RFID tag being in a detectable range of the RFID reader. The RFID reader can also be for transmitting information about the RFID tag for controlling a motor to rotate and position the drive shaft at a selected angular position.
