Stop coreapi displaying the admin api docs

I am currently documenting the API I have created for an app.

I'm using the built in documentation system that comes with Django Rest Framework and coreapi (as described here).

class MyAPI(APIView):

    schema = ManualSchema(fields=[coreapi.Field(...), ...],
                          description='Describe this view')

I set up the url for the docs in the urls.py for the API app:

url_patterns = [
    url(r'^docs/', include_docs_urls('My API Title')),
    ...
]

The problem I have is that when I visit the docs I see the admin API docs alongside my API docs.

I've tried using the answer to this question:

REST_FRAMEWORK = {
    'DEFAULT_RENDERER_CLASSES': (
        'rest_framework.renderers.JSONRenderer',
    )
}

But the admin docs still show up.

Is there a way to hide the admin docs?
