   Several based on short stories, in fact.  Mostly in the "newer"   
   incarnation, the one in the 90's:   
      
   "The Human Operators" - AE Van Vogt & Harlan Ellison (1999 airing)   
   "Inconstant Moon" - Larry Niven (1996 airing)   
   "The Sandkings" (ooh that was creepy!) - George RR Martin (1995   
   airing)   
   "I, Robot" - Eando Binder (1964 airing)   
   "Soldier"  (yeah - I was surprised it came from a short story...) -   
   Harlan Ellison (aired 1964)   
      
   You are, however, mostly correct, as far as I can see.  Most were   
   written as screenplays.   
      
   There is one, too that I saw (can't remember the name at all) about a   
   (cyborg? modified animal like a wolf?) who was a "hunter" or an   
   assassin.  Only remember it because I had just got done reading the   
   short story several weeks before - then saw this episode.
