def stop_actions(self):
        """
        Returns a list of stop actions supported by the motor controller.
        Possible values are `coast`, `brake` and `hold`. `coast` means that power will
        be removed from the motor and it will freely coast to a stop. `brake` means
        that power will be removed from the motor and a passive electrical load will
        be placed on the motor. This is usually done by shorting the motor terminals
        together. This load will absorb the energy from the rotation of the motors and
        cause the motor to stop more quickly than coasting. `hold` does not remove
        power from the motor. Instead it actively tries to hold the motor at the current
        position. If an external force tries to turn the motor, the motor will 'push
        back' to maintain its position.
