decorator - Python Sphinx autodoc and decorated members

Question

I am attempting to use Sphinx to document my Python class. I do so using autodoc:

.. autoclass:: Bus
   :members:

While it correctly fetches the docstrings for my methods, those that are decorated:

    @checkStale
    def open(self):
        """
        Some docs.
        """
        # Code

with @checkStale being

def checkStale(f):
    @wraps(f)
    def newf(self, *args, **kwargs):
        if self._stale:
            raise Exception
        return f(self, *args, **kwargs)
    return newf

have an incorrect prototype, such as open(*args, **kwargs).

How can I fix this? I was under the impression that using @wraps would fix up this kind of thing.

To expand on my comment:

Have you tried using the decorator package and putting @decorator on checkStale? I had a similar issue using epydoc with a decorated function.

As you asked in your comment, the decorator package is not part of the standard library.

You can fall back using code something like the following (untested):

try:
    from decorator import decorator
except ImportError:
    # No decorator package available. Create a no-op "decorator".
    def decorator(f):
        return f
