Is there an adapter to allow a camera to control focus or aperture of a manual focus & aperture lens?

I recently bought the Sony Alpha a7. In a bid to get an affordable portrait lens, I rushed to get the Rokinon 85mm f/1.4 only to realize that there is no communication between the camera and lens. Now that I now understand how a manual lens works, I was wondering if there is any adapter of some sort that can help with either controlling the aperture or focus from the camera, or even both?
