     To reduce the amount of RX calibration data that needs to be generated,
-    :class:`qiskit.transpiler.passes.optimization.normalize_rx_angle.NormalizeRXAngle`
+    qiskit.transpiler.passes.optimization.normalize_rx_angle.NormalizeRXAngle
     performs three optimizations: wrapping RX gate rotation angles to [0, pi], 
     replacing RX(pi/2) and RX(pi) with SX and X gates, and quantizing the rotation angles.
     This pass is required to be run before 
-    :class:`qiskit.transpiler.passes.calibration.rx_builder.RXCalibrationBuilder`,
+    qiskit.transpiler.passes.calibration.rx_builder.RXCalibrationBuilder,
     which generates RX calibrations on the fly.
 
     The details of the transpiler passes are as follows:
-    :class:`qiskit.transpiler.passes.optimization.normalize_rx_angle.NormalizeRXAngle` wraps
+    qiskit.transpiler.passes.optimization.normalize_rx_angle.NormalizeRXAngle wraps
     RX gate rotation angles to [0, pi] by replacing an RX gate with negative rotation angle, RX(-theta),
     with a sequence: RZ(pi)-RX(theta)-RZ(-pi). Moreover, the pass replaces RX(pi/2) with SX gate,
     and RX(pi) with X gate. This will enable us to exploit the more accurate, hardware-calibrated
     pulses. Lastly, the pass quantizes the rotation angles using a user-provided resolution.
     If the resolution is set to 0, this pass will not perform any quantization.
-    :class:`qiskit.transpiler.passes.calibration.rx_builder.RXCalibrationBuilder`
+    qiskit.transpiler.passes.calibration.rx_builder.RXCalibrationBuilder
     generates RX calibrations on the fly. The pulse calibrations are bootstrapped from 
     the SX gate calibration in the target.
     The amplitude is linearly scaled to achieve the desired arbitrary rotation angle.
