    You do not pass Socket instances to this, but rather Socket types::

        Device(device_type, in_socket_type, out_socket_type)

    For instance::

        dev = Device(zmq.QUEUE, zmq.DEALER, zmq.ROUTER)

    Similar to zmq.device, but socket types instead of sockets themselves are
    passed, and the sockets are created in the work thread, to avoid issues
    with thread safety. As a result, additional bind_{in|out} and
    connect_{in|out} methods and setsockopt_{in|out} allow users to specify
    connections for the sockets.
    
    Parameters
    ----------
    device_type : int
        The 0MQ Device type
    {in|out}_type : int
        zmq socket types, to be passed later to context.socket(). e.g.
        zmq.PUB, zmq.SUB, zmq.REQ. If out_type is < 0, then in_socket is used
        for both in_socket and out_socket.
        
    Methods
    -------
    bind_{in_out}(iface)
        passthrough for ``{in|out}_socket.bind(iface)``, to be called in the thread
    connect_{in_out}(iface)
        passthrough for ``{in|out}_socket.connect(iface)``, to be called in the
        thread
    setsockopt_{in_out}(opt,value)
        passthrough for ``{in|out}_socket.setsockopt(opt, value)``, to be called in
        the thread
    
    Attributes
    ----------
    daemon : int
        sets whether the thread should be run as a daemon
        Default is true, because if it is false, the thread will not
        exit unless it is killed
    context_factory : callable (class attribute)
        Function for creating the Context. This will be Context.instance
        in ThreadDevices, and Context in ProcessDevices.  The only reason
        it is not instance() in ProcessDevices is that there may be a stale
        Context instance already initialized, and the forked environment
        should *never* try to use it.
