     k: integer specifying the number of top entries.
 
   Returns:
-    values: array containing the top k values along the last axis.
-    indices: array containing the indices corresponding to values.
+    A tuple ``(values, indices)`` where
+
+    - ``values`` is an array containing the top k values along the last axis.
