    """Create an output key to be used by a Transform instance.

    This method is used to create unique, easily-identifiable output keys
    for Transform instances. *args and **kwargs are used purely for
    ensuring key uniqueness, and need not be arguments to the Transform's
    initializer, though they generally will be, for ease of interpretability.

    :param transform_name: The name of the Transform class.
        This argument is generally passed via the __name__ attribute of
        a class. Note that we do not simply pass the class itself (which
        would be the more intuitive approach), as Ray wraps actor classes
        in its own wrapper class, which will cause the __name__ attribute
        to return an unexpected value.
    :param *args: Variable length argument list.
    :param **kwargs: Arbitrary keyword arguments.
