Inconsistent docstrings

I observed that the documentation is somehow autogenerated via sphinx. However a lot of function and class signature docstrings are very inconsistent and don't use the sphinx syntax.

Can you point to specific instances where the docstrings are inconsistent?

I attached a patch with three commits (2 of them are about some docstrings, that i stumbled over the other is about abstract methods)
