Please do no use AI to make changes and write the PR description in this manner. There are a lot of changes we have not asked for.

I wont just close this for now but stick to docstrings. Avoid making text changes other than typos and the requested alterations. Do not completely replace docstrings. View the failing test to ensure that your changes meet our code quality standards.
