        Defines an abstract base class for SPI modules. All module drivers
        should inherit from this class.

        This class defines no actual functionality but rather serves to
        provide a common interface shared among all modules.

        Parameters
        ----------
        parent
            Reference to the :class:`~qblox_instruments.native.SpiRack` parent
            object. This is handled by the
            :func:`~qblox_instruments.native.SpiRack.add_spi_module` function.
        name : str
            Name given to the module.
        address : int
            Module number set on the hardware (set internally on the module
            itself with a jumper).

        Returns
        ----------

        Raises
        ----------
