Answer 1

I solved it using this approach instead:

class ParamsHandler_Meta(type(QObject), type(abc.ABCMeta)):
    pass
class ParamsHandlerClass(QObject):
    pass
class ParamsHandler(ParamsHandlerClass):
    __metaclass__ = ParamsHandler_Meta
    def __init__(self, device_model, cmd_to_get_data, read_only=False):
        super(ParamsHandler, self).__init__()
        self.cmd_to_get_data = cmd_to_get_data

    __metaclass__ = abc.ABCMeta
