Controller still includes not longer used infos

The @param and @return values in the header function are obsolete

Not all the infos should be removed. Some of them could be used by phpstan or other tools. We have to look, which we can remove or not

I don't know how PhpDoc is handling it now.
As those things could be useful for automated documentation, it could be beyond functional aspects.
