+The following information is available in the `screws_tilt_adjust`
+object:
+- `error`: Returns True if the most recent `SCREWS_TILT_CALCULATE`
+  command included the `MAX_DEVIATION` parameter and any of the probed
+  screw points exceeded the specified `MAX_DEVIATION`.
+- `results`: A list of the probed screw locations. Each entry in
+  the list will be a dictionary containing the following keys:
+  - `name`: The name of the screw as specified in the config file.
+  - `x`: The X coordinate of the screw as specified in the config file.
+  - `y`: The Y coordinate of the screw as specified in the config file.
+  - `z`: The measured Z height of the screw location.
+  - `sign`: A string specifying the direction to turn to screw for the
+    necessary adjustment. Either "CW" for clockwise or "CCW" for
+    counterclockwise. The base screw will not have a `sign` key.
+  - `adjust`: The number of screw turns to adjust the screw, given in
+    the format "HH:MM," where "HH" is the number of full screw turns
+    and "MM" is the number of "minutes of a clock face" representing
+    a partial screw turn. (E.g. "01:15" would mean to turn the screw
+    one and a quarter revolutions.)
