I would have added the following labels to this PR based on the changes made: [ $\color{#41A8F6}{\textsf{transformations}}$ ], however some package labels are already present.

The Checks tab will show the status of our automated tests. You can click on individual test runs in the tab or "Details" in the panel below to see more information if there is a failure.

If our pre-commit code quality check fails, any trivial fixes will automatically be pushed to your PR unless it is a draft.

Don't hesitate to ask questions on the aeon Slack channel if you have any.

Apart from these two minor comments, everything LTGM !

Some possible very sneaky bugs, it may not be, but It can be a pain to debug if not checked early on.

Potential issues with reshape seem to be fixed !
It may a good idea to include a consistency test between CPU & GPU versions (i.e. test that a same-seeded transform output the same results for both versions with an assert_array_almost_equal).
If you feel like this fits into another PR, we can close this one and raise an issue to work on it later.

Happy to do both, but maybe putting it as a feature request can be a good first issue for new contributors.
