“take over” is a human, fuzzy concept, the exact application of which is context-dependent. And it’s still useful. Any of “determining the direction and speed the horse goes next”, “deciding whether to feed or starve the horse”, “locking the horse in a barn to prevent it being ridden” or lots of other activities can be put under the heading “taking over”.
If the details matter, you probably need to use more words.
